Ubuntu operating system is distributed for free and is free to download. The latest version of Ubuntu will always be downloaded from the official site.

You already have a few choices you need to make. There is (except for six months every two years) the LTS release (Long Term Support) and the latest cutting edge release. While both are usually considered stable enough for everyday use, the LTS release is more stable and is supported for five years from its release date. The releases in between LTS releases are only supported for nine months so you must upgrade to a newer release every six months if you go that route. However, if you’re having hardware issues on an LTS release, you’ll probably find better support for your hardware on the cutting edge releases.

Then there’s the question of choosing 64-bit and 32-bit. Nowadays, you should always pick 64-bit unless you know that your computer is too old and cannot support it. There used to be a general “rule” floating around saying that you shouldn’t use 64-bit unless you have 3GB of RAM or more, but you can ignore that. All systems should take advantage of 64-bit even if they have smaller amounts of RAM.

We have different types of Ubuntu operating systems, they are Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud and Ubuntu for Mobile devices and Tablet.
